hi

i woukd like to attach some custom data to the album and the image

example
album may have an image map to use in its description.

image may have some additonal field can be used for pushing custom data to display.
anyway to do so ?

i am not a programmer to code and integrate into backend as well as theme coding.

Also in admin section there are location and custom data input area and I have no clue if I can use them to insert and show custom things over there in zpBase theme.

There are functions for these fields:
https://docs.zenphoto.org/function-getAlbumLocation.html
https://docs.zenphoto.org/function-getImageLocation.html
https://docs.zenphoto.org/function-getAlbumCustomData.html
https://docs.zenphoto.org/function-getImageCustomData.html

You will have to edit your theme to use these. Or you can use codeblocks. But if the them has no support for theme you will also have to modify the theme.
